Default electronic ballast repair


ha scritto nel messaggio

Hello all,

This little electronic ballast for a 11W fluorescent tube (2 pin one)
failed.
I found a bad electrolitic a fried 1.2 ohm resistor and a shorted
active device which I failed to identify. Looks like a TO-126
transistor, it is marked Si 1300313.
There's another identical transistor, but either is burned too (but
not shorted like the other) or isn't either BJT nor mosfet as every
terminal has some measurable resistance (in the hundreds of ohms
range) with every other terminal, either polarity (but resistance is
different with polarity reversed).
Any hint on how to identify this? Would be easier to just buy another
one, but this stupid thing failed after only 8 months use, I wouldn't
want to change ballasts more often than lamps.


Francesco, have a look at Todis hard discount.
They have complete set, case-switch on it-cable and plug, at 4,50 euro only.
Just ready to fit and eventually extend to others 'cause have fitted on side
an extension socket.
Not worth to repair.
ciao Valerio
